More Information
Summary:A low-nitrogen combustion state analysis and optimization control method based on hearth pressure comprises a pressure sampling point, a high-precision absolute pressure gauge, a high-precision differential pressure transmitter, a data processing module, a calculation station, a DCS interface, a soot blowing pipeline and a valve. The pressure sampling point is positioned in a high-temperature area of the combustor and is respectively connected with pipelines of the high-precision absolute pressure gauge and the high-precision differential pressure transmitter through pressure sampling pipes; and the data processing module is electrically connected with the computing station. The boiler does not need to be additionally transformed, and is simple in structure, easy to implement, low in cost and convenient to operate. The system can monitor the oxygen concentration of the main combustion area and the temperature of the high-temperature area of the combustor in real time, so that a boiler can flexibly adjust the
